Application filed July 29, 1924-.

To all whom it may concern:

Be it known that WILLIAM G. LnAzAR, a citizen. of the United States ofAmerica, re-

, sidin at. Kerrville, in the county of Kerr and tate of Texas,has-invented new and useful Improvements in Riveting Apparatus, of whichthe following is a specification. fiIt is a purpose of the presentinvention to provide, in a riveting apparatus, a constructionparticularly adapted for riveting arms upon crank cases, especiallythose of the Ford type, and in carrying this process into elfecttheinvention includes a riveting block with means for fastening themsameon a bench or a horse, whereby the crank case may be placed so that,when the rivets which are to securethe arms to the crank case engagewith thezblock', in' iproved clamps are used to. fasten: the crank-casein position, subsequently towhicha mechanic may proceedl to heat therivets with a torch and set them with a riveting-setor hammer.

T -It is to be understoodthat the particulars herein given are in no.v-say. limitative and that, whilestill keepingwithin thescope of theinvention, any desired modifications of:

detail .and- .desired' proportions may be: made in. the apparatusaccording to the circumstances; I 7:, r

In the drawings: I

Figure 1 is a view of the improved riveting. app'aratus constructed inaccordance with the invention and illustrating a crank case in positionthereonfor' riveting the arms in position.

Figure 2 is a central vertical sectional view of the invention,illustrating how the rivets engage with the riveting block and how theclamps are applied.

Figure 5 is a detail view of a portion of the support 16 and the holder20.

Referring to the drawings, 1 designates the riveting block which isprovided with a pair of projections 2 and 3 which are cesigned to enteropenings 4 and 5 of corresponding size to the diameter of theprojections, said openings being formed in a bench,

The invention having been setforth, what is claimed is:

1. A riveting apparatus for riveting arms on crank cases, the samecomprising a riveting block provided with means for holding it ona benchor other support, a supporting member carried by the riveting block andhaving a laterally projecting arm, a holder suspended from said arm andadapted to support a crank case at a point remote from the rivetingblock, and a clamp operatively supported on the riveting block forbearing engagement upon a crank case arm and holding it in contact withthe crankcase and the latter in contact with the riveting block.

2. A riveting apparatus for riveting arms on crank cases, the samecomprising a riveting block provided with means for holding it on abench or other support, a supporting nemher carried by the rivetingblock and having a laterally projecting arm, a holder suspended fromsaid arm and adapted to support a crank case. at a point remote from theriveting block, and a clamp operatively supported on the riveting blockfor hearing engagement upon a crank case arm and holding it in contactwith the crank case and the latter in contact with the riveting block,

said clamp comprising a goose-neck arm detachably engaged in a seat onthe riveting block.

3. A riveting apparatus for riveting arms on crank cases, the samecomprising a riveting block provided with means for holding it on abench or other support, a supporting member carried by the rivetingblock and having a laterally projecting arm, a holder suspended fromsaid arm and adapted to support a crank case at a point remote from theriveting block, and a clamp operatively supported on the riveting blockfor hearing engagement upon a crank case arm and holding it in contactwith the crank case and the latter in contact with the rivetingblock,said support comprisinga bar having a U- shaped extremity disposed atright angles to the projecting arm, tremity straddling and engaging arecess in the riveting block.

4. A rivetingapparatus for riveting arms on crank cases, the samecomprising a riveting block provided with means for holding it on abench or other support, a supporting member carried by the rivetingblock and having a laterally projecting arm, a holder suspended fromsaid arm and adapted to support a crank case at a point remote from theriveting block, and a'clamp operatively supported on the riveting blockfor bearing engagement upon a crank case arm and hold ing it in contactwith the crank case and the latter in contact with the riveting block,said support comprising a bar having a U- shaped extremity disposed atright angles to,

the projecting arm, said U-shaped extremity straddling and engaging arecess in the riveting block, and the holder being suspended from thearm and movable longitudinally therealong. i

In testimony whereof he affixes his signature.
